Abstract

Abstract Plasma pre-treatment represents the key enabler technology for microfine cleaning, surface activation and plasma coating of almost all types of materials — from plastics, metals and glasses to textiles, composites and photographs. More and more conventional industrial treatment methods are being replaced by plasma technology in order to make processes more effective and environmentally friendly. This study is oriented on the characterization of a photographic image on two types of photographic paper (glossy and matt photographic paper with a barite layer), and monitoring the effects induced by the Atmospheric Discharge with Runaway Electrons (ADRE) plasma in air atmosphere on the photographic image layers. To evaluate their long-term stability before/after plasma treatment, degradation of black and white gelatin photographic components upon accelerated light aging using Q-SUN was investigated and the photoinduced changes were recorded by FTIR spectroscopy, densitometry and colorimetry. The results obtained demonstrated that the plasma discharge had no significant destructive effect on the photographic image as only negligible changes in the structure of the gelatin were detected due to plasma processing. Consequently, it can be concluded that low-temperature ADRE plasma in air atmosphere has the potential for successful applications in microbial decontamination and purification of damaged gelatin photographs.
等离子体处理明胶摄影
等离子体预处理是几乎所有类型材料(从塑料、金属和玻璃到纺织品、复合材料和照片)的微细清洗、表面活化和等离子体涂层的关键技术。越来越多的传统工业处理方法正被等离子体技术所取代,以使处理过程更有效和环保。本研究针对两种类型的照相纸(有重晶石层的光面照相纸和亚光照相纸)上的摄影图像进行表征,并监测大气中失控电子大气放电(ADRE)等离子体对摄影图像层的影响。为了评价其在等离子体处理前后的长期稳定性,采用Q-SUN研究了黑白明胶照相成分在加速光老化过程中的降解情况,并通过FTIR光谱、密度测定法和比色法记录了光致变化。结果表明,等离子体放电对照相图像没有显著的破坏性影响,因为等离子体处理只检测到明胶结构的可忽略不计的变化。因此,可以得出结论,低温ADRE等离子体在空气气氛中具有成功应用于微生物去污和纯化受损明胶照片的潜力。
